I got it to work by using vtkDICOMImageReader to read the DICOM slice files in Medical3.cxx and then i need to generalize the extent of the image and other things to make the sagittal, cronal and axial blades to center at iso center of volume. I am not happy with coloring of this this, In medical3 there are bwlut, huelut, and salut if i am not mistaken, but bwlut for sagittal is disastrous for center slice at least and you dont see much it is almost completely white with some black segments with are related to perhaps some tissues in back of the subject. bone and skin i removed in the Image3.cxx and also tried to figure out how to make the black and white segmented sagittal look like.
The strangest thing is that i have check these slices in paraview and they look not sharp but sort of output of Gaussian lowpass filter !?
any suggestions? these dicom slices come from TCIA site/head&neck CT, sort of not happy with the contrast, brightness, colors, how to pick out a tumor of sort of very at early stages of tumor? not happy with image quality!
any help to fix color tables saturation, hue, brightness would be appreciated!
